Description
本発明は、不感(外部刺激に強い)な大砲弾においては、不感爆薬(IHE)と砲弾壁との間には、IHEと弾莢の熱膨張の違いに基づく熱的な応力が生じるのを防止するために、直接的な接触がない。従って、両者の間においてライナー、通常プラスチック袋、が弾莢内へ挿入される。次に、IHEが、注ぎ込まれて、硬化される。 According to the present invention, in a cannonball that is insensitive (strong against external stimuli), thermal stress is generated between the insensitive explosive (IHE) and the shell wall based on the difference in thermal expansion between IHE and the shell. There is no direct contact to prevent. Therefore, a liner, usually a plastic bag, is inserted between the two into the grenade. Next, IHE is poured and cured.
大口径の爆裂弾を形成する方法とこの方法に従って形成された爆裂弾が、特許文献1に開示されている。ここでは、温度変動の際に変化する爆薬の体積が、弾性的なプラスチックジャケットによって吸収されるようにするために、弾性的な材料製のプラスチックジャケットからなるライナーが提案される。ライナーの挿入は、通常頭部信管を収容するために用いられる、砲口を通して、折りまとめ、あるいは圧縮した形状で、行われる。展開した状態において、この袋状に形成されたプラスチックジャケットは、爆裂弾の内部空間の寸法に相当する。 Patent Document 1 discloses a method for forming a large-diameter bomb and a bomb formed according to this method. Here, a liner consisting of a plastic jacket made of an elastic material is proposed in order to allow the elastic plastic jacket to absorb the explosive volume that changes with temperature fluctuations. The insertion of the liner is done in a folded or compressed shape through the muzzle, usually used to house the head fuse. In the unfolded state, the plastic jacket formed in a bag shape corresponds to the size of the inner space of the bomb.
幾つかの場合においては、ライナーは、爆薬の膨張に応じて発生する自己の熱膨張を補償することができるように、固くない。熱膨張が大きいことに基づいて、爆薬は、冷却/加熱の際に数mmだけ収縮し、ないしは膨張する。ライナーは、爆薬と共に収縮するが、同じ程度には一緒に膨張しない。それによって爆薬上でライナーの移動がもたらされる。ライナーは、多数の温度変化を介して爆薬に対して後方へ移動するので、爆薬が部分的に露出することがある。 In some cases, the liner is not stiff so that it can compensate for its own thermal expansion that occurs in response to the expansion of the explosive. Based on the large thermal expansion, the explosive contracts or expands by a few mm during cooling / heating. The liner contracts with the explosive but does not expand together to the same extent. This results in movement of the liner over the explosive. As the liner moves backward relative to the explosive through a number of temperature changes, the explosive may be partially exposed.
ここで、本発明の課題は、爆薬上でのライナーの移動を防止する、ことである。 Here, an object of the present invention is to prevent movement of the liner on the explosive.
この課題は、特許請求項1の特徴によって解決される。好ましい形態が、下位請求項に記載されている。 This problem is solved by the features of claim 1. Preferred forms are described in the subclaims.
本発明の基礎となる理念は、ライナー内に、爆薬前端縁に対して、あるいは爆薬内に、形状結合を実現する、ある種の隆起部または突片をライナー内へ取り付け、ないしは形成することである。 The philosophy underlying the present invention is to attach or form certain ridges or protrusions in the liner, to the leading edge of the explosive, or in the explosive, to achieve a shape connection. is there.
特許文献2からは、スプリット外皮を有する砲弾が知られており、その中には箔で包囲された爆薬が配置されており、鋼、銅またはプラスチックからなることができる、この箔は、砲弾の長手方向に延びる、列をなして配置された幾つかの細長い湾入部を有しているが、この湾入部は、小さい中空装薬を形成するために用いられ、それが、爆薬を有する箔を包囲する、円筒状のスプリット外皮へ向けられている。爆薬体が爆発する際に、小さい中空装薬によってスプリット外皮に切欠きが形成され、外皮がこの切欠きに沿って破片に分裂する。破片の大きさは、列の湾入部の間の間隔と列間の間隔に相当する。爆薬に対して箔を固定するための利用は、考えられていない。 From US Pat. No. 6,057,086, a shell having a split shell is known, in which an explosive surrounded by a foil is arranged, which can be made of steel, copper or plastic. It has several elongated bays arranged in a row extending in the longitudinal direction, but this bay is used to form a small hollow charge, which is a foil with explosives. It is directed to the surrounding cylindrical split skin. When the explosive body explodes, a small hollow charge forms a notch in the split skin, and the skin splits into fragments along this notch. The size of the debris corresponds to the spacing between the bays of the rows and the spacing between the rows. Use to fix foil against explosives is not considered.
その場合に、隆起部は、一周して形成することができる。ライナーが折り畳まれた形状で弾莢内へ挿入される場合に、一周する隆起部のセグメント化が提供される。その際に生じる突片は、同時に、極めて高い形状剛性を有しており、間隙がライナーの簡単な折り畳みを可能にする。 In that case, the raised portion can be formed in one round. When the liner is inserted into the grenade in a folded configuration, a segmentation of the ridge that goes around is provided. The resulting protrusions have at the same time a very high shape stiffness and the gap allows for easy folding of the liner.
突片の形状剛性を高めるために、たとえば、突片の領域内で壁厚/材料厚が増大されることによって、突片の剛性を所望に調節することが、推奨される。隆起部の幅と奥行きによっても、変化が可能である。 In order to increase the shape rigidity of the protrusion, it is recommended to adjust the rigidity of the protrusion as desired, for example by increasing the wall thickness / material thickness in the region of the protrusion. Changes are also possible depending on the width and depth of the ridges.
ライナー内に複数列の隆起部または突片を設けることも、効果的であることが明らかにされている。 Providing multiple rows of ridges or protrusions in the liner has also proved effective.
突片または隆起部は、ライナー工具の簡単な修正によって、ライナーを形成する際にライナー内に形成することができる。 The protrusions or ridges can be formed in the liner when forming the liner by a simple modification of the liner tool.
図面を有する実施例を用いて、本発明を詳細に説明する。 The invention is explained in detail by means of an embodiment with the drawing.
図1は、弾莢2、弾莢と爆薬4の間に配置されたライナー3を有する砲弾1を部分的に示している。爆薬4上でライナー3が滑るのを防止するために、ライナー3の、爆薬表面に対して定められた箇所L1に、内側へ向けて成形された隆起部/突片5が形成されている(図1a)。隆起部5は、ライナー3がそれぞれ爆薬4の充填高さに応じて即座に、あるいはわずかな温度サイクルの後に、爆薬4の前端縁に相補形状で添接するように、硬く形成されている。
FIG. 1 partially shows a shell 1 having a shell 2 and a
図2は、1つより多くの、形成された隆起部ないし突片5(図2a)を有する砲弾1を示している。この場合に他の隆起部6は、爆薬表面に対して定められた長さL2において、ライナー3内へ挿入されて、爆薬4を注ぎ込む際にすでに相補形状で係止されることができ、従って初めから固定されることを、可能にしている。
FIG. 2 shows a cannonball 1 having more than one formed ridge or protrusion 5 (FIG. 2a). In this case, the other ridge 6 can be inserted into the
ここでは原理的に、ここでも、知られているように、不感爆薬4が大砲−砲弾1内へ注ぎ込まれることを、前提としている。爆薬4が弾莢2の内壁に付着するのを回避するために、弾性的なゴム状のプラスチックジャケットの形状の、ライナー3が挿入される。弾莢内への挿入は、砲口7を通して行われる。不感爆薬4は、爆薬と他の添加物を有するプラスチック結合剤系からなる。爆薬は、ライナー3内へ注ぎ込まれて、そこで硬化する。従って、硬化された、成形された爆薬が、プラスチック結合された爆薬4を形成する。爆薬4は、鋼からなる弾莢2に対して、係数が8乃至12だけ大きい温度膨張係数を有している。
Here, in principle, it is also assumed here that, as is known, the insensitive explosive 4 is poured into the cannon-bomb 1. In order to avoid the explosive 4 from sticking to the inner wall of the shell 2, a
